Summary
The world is full of food, but in order to make the most of it, living organisms need to be able to break it down and extract the useful nutrients. This episode, we explore the fundamental process of digestion and the many, many ways that life has adapted this process to various diets. And we’ll take a look at what the fossil record has to tell us about ancient diets and the evolutionary history of digestive systems. In the news: predator bites, coelacanth lungs, Cambrian claws, and squid evolution.
